i will speculate about the routes
it would be either "south america - africa - europe - asia - U.S" or "Europe - Africa - Asia - Oceanian - South america - U.S"
Brazil has never been visited since season 18. so it would be a contender. India has also never been visited since season 20. it would also be a top contender. Indonesia, which has never been visited would also be a top contender
( you know i'm kidding right, ) so btw here are my top contender countries
- Brazil ( not Rio De Janeiro please)
-China ( would love this country to be a penultimate, it's been 7 seasons, Beijing or Tianjin could be visited as well)
-India ( starting to miss it)
-Philippines ( like really, i can see how fans from philippines can't wait for its visit)
-Czech Republic or Hungary ( i see how AR is actually spreading their visits throughout the entire seasons, Czech republic hasn't been visited since season 15 and Hungary since season 6, they're beautiful and would make a good intense 4th or 5th leg)
-all african countries except the ones which are dangerous and have been recently ( i want gabon and it's safe, however african countries are always chosen randomly)
-Australia ( however, Australia was also visited in the last all star so the probability will be lower than the others)
-oceanian countries ( Fiji, Tonga, Samoa, just mention it, they're all beautiful exotic countries and completely safe. curious about them being penultimate legs.)
